RAILROAD SIGNAL nEvIcEf.'

i To all whom it mag/concern. 1,

Be it known that we, .SrnrANfNIKEn ar citizen of, Poland, residingatVNew York, county of New,York,andStateof New Yorlnvand THQMASLISTOSKI, a citizen of `Poland, residing at `l\TewYork, county of New York, and State ofNew York, have mf ger of collision.v

i become` more fullyapparent as the descripf are attainedy `by the novel y,

tion progresses,

view taken in the vicinity of the numeral 15 indicates a vented certain newand `useful Improyements in Railroad Sfgnal Devices,` of which the following is a specii cation. l

This invention has 4as its object the provision of track-sidedevices whereby'danger or like signals maybe displayed inadvance of an approaching train, ini such manner -as to warn the operator of the impending dan- .A further objectfisto provide tra'ckesidefV deviceswhich are automatically Yjo erated by the Vpassing train and without er Operator.` z L f.

`These `and other like objects, which will construction and combination of partshere inaftery described, and shown in the jaccom panying drawings, forming a material part of this disclosure, and in whichm Figure V1isa lan viewshowin a rail track sectionjhaving a branch crossing over. `anothertrack parallel with the first, and 1ndicating the application of the invention.

Fig. 2 is an enlarged fragmentary plan numeral 2 on Fig. 1. U

Fig. 3 is a transversesectional view taken on line 3-3 of Fig. 2.

Fig. 4 is an enlarged longitudinal Sectional view taken through a pair of the track-side devices.

Fig. 5 is a top plan view of the same, the covers being removed, and

Fig. 6 is a vertical sectional view taken on line 6-6 of Fig. 4.* i n A.Referring to the drawings in detail, the conventional type of straight or through track having abranch 16, the Same crossing another track 17 `at an oblique angle.

Mounted adjacent to one of the track rails on each track, in advance of the crossing, or branch, are relatively narrow, rectangular metallic casings 18, from which lproj ect plungers 19, while upon the voppositeside of the curve, are similar but smaller casings 20, having extending plunger heads 21. j

Extending below the plunger heads 21 are l Specicationof Letters 1atent.

verticalilstems 22,.'slidably engaged with bracketsl 23, `andjpivotally connected at their lower e ends .by pins r24 with the horizontal arms,` 25,y ofi bell-cranlrlevers,'pivoted on' spindles26 passing transversely through the i casings 20, the vertical arms k27 4of the bellcrank levers being pivoted to rods 28, which extend closely adjacent tothe track rails to thecasings 18.; r s

These rods engagethe arms 29 `of bellcrank levers, pivoted on spindles 30 passing transversely .through the" casings, the other arms'31zof the/bell-crank levers being forked and containingslots 32 engaging pins k33 setH inthe levers 34, pivotedon spindles 335, carried-ininsulating elements 36 and 37 secured totheinner surfaces of thecasing walls. The levers 34y are normally held. in raised position, due to coiledfy compression springs 38, extending from the bottom of the casings upward to the levers, whichflevers have formed `upon their ,upper Sides detents 39, the purpose of which will be further on described. y. j

v i Extendi elements 40, are stems41 kforrned ywith the plunger' headsfl9, .these stems being rigid withk angularly` disposed levers 42, ful crumed.onfspindles 43, held by insulating elements 44 and 45 to the walls of the casing .g downward ythrough `insulating 'z 18, while extending downwardffrom the opi posite sides of the axes 43, from the levers 42 are arms 46, normally drawn toward the f end of the box by coiled tension springs 47, the ends of the arms normally resting upon the detent portions 39 of the levers 34, and which may be engaged thereby when the plungers 19 are depressed, permitting the detents'to rise 'and engage lwith the lever ends of the arms.

Engaged with the spindles 43 are electric conductors 48, leading from one pole of the batteries 49, the other pole of the .batteries being similarly connected with electric con-k ductors 50, engaged with brackets 51, secured to insulating elements 37, thesebrackets having inwardly extending arms 52, contactable with similar arms 53, 'slidably engaged with the lever arms 46, and pressed vnormally outward, due to the effect of bent flat springs 54, the arrangements being such that when the flanges of the wheels of a passing `train make contact with the plunger 19 as to depress the same, causing electrical contact between the conductors 4S andO, the same remains in contact, due to the arm lG, being held by the detent 39, until the train is further advanced and the Wheels make Contact With the plunger 2l, operating the bell-crank levers connected 'therebetween to depress the detents 39, thereupon the springs 47 raise the tion for further operation.

lVhen the contacts 52 and 53 are in engagement, a circuit is formed through Wires 48 and 50, energizing the electric lighting signals V55, visibly announcing that the train is approaching a dangerous location.

At the intersection of the curved track and straight track, indicated by the numeral 2, the connecting rods 28 are engaged by a pin56 with a slot 57 in the lever 58, fulcruined at` 59, and also connected by thefpin 56 is the outer end of a diagonally'disposed lever28, so as to transmit rectilinear movement throughout the linked connection in a smooth and easyman'n'er.

From the foregoing it will be seen that an effective signal operating device has been disclosed, whichy is automatically operated by the passing of the train, the signals showing clearly Whether or not the adjacent track sections are free to move upon or if a train is approaching thereon.

Having thus described my invention what I claim as nevi7 and desire to secure by Letters Patent, is-

l. In a railway signal device, the combination with track side devices consisting of make and break elements, casings therefor, a source of electrical energy, and connections between said source of elect ical energy and one of said contact elements, of a plunger extending above one of said casings,said plunger kbeing insulated from the Walls thereof plungers 19 into posi-` and engaged with one of said electric elements, a fixed arm in said casing 4engaged With the other of said electric elements, a detent lever pivoted in said casing engageable with said arm `whereby said elements are held when in engagement, fixed connections extending from said detent lever to the other of said casings, a plunger mounted in the other casing, and `linked connections therebetween whereby said detent lever is released upon the passing of a train over the plunger in ,saidv'second easing.

\ 2. In a :railway signal device, lthel combination with a plurality of tracks, a source of'el'ectrical energy, signals inv circuit there- With, vand a trackside casing, of a plunger movable in said' "track-side casing, an arm therein, a conductor from said source of electrical-energy communicating with said arm a iXed bracket in said casing, from the opposite pole 'offs'aid source of electrical energy connected with said fixed bracket, springcontactscarried by saidarm adapt-ed to engage vsaid fixed bracket, a detent leverpivo'ted in said casing, means for normally pressing said detent 'lever upward so as "to ycause engagement with said arm, a

bell-crank ipivoted in said casing, a. second easing'rem'o'te from the first, a plunger therein., a bell-crank lever engaged With said plunger at'one end, and an operative connection With said levers `whereby said arm isr lreleased simultaneously vupon depressing said'second plunger.
